bazaltina [42]2 years ago

Answer:

x=2<br/>y=1

Step-by-step explanation:

\left\{ \begin{array} { l } { 4 x + y = 9 } \\ { 3 x - 2 y = 4 } \end{array} \right.

4x+y=9,3x-2y=4

4x+y=9

4x=-y+9

x=\frac{1}{4}\left(-y+9\right)

x=-\frac{1}{4}y+\frac{9}{4}

3\left(-\frac{1}{4}y+\frac{9}{4}\right)-2y=4

-\frac{3}{4}y+\frac{27}{4}-2y=4

-\frac{11}{4}y+\frac{27}{4}=4

-\frac{11}{4}y=-\frac{11}{4}

y=1

x=\frac{-1+9}{4}

x=2

x=2,y=1

Explain how you could write a quadratic function in factored form that would have a vertex with an x-coordinate of 3 and two dis
KATRIN_1 [288]
The vertex is on the axis of symmetry, so the axis of symmetry is x = 3. Find any two x-intercepts that have the equivalent distance from the axis of symmetry. Use those x-intercepts to write factors of the function by subtracting their values from x. For example, 2 and 4 are each 1 unit from x = 3, so f(x) = (x – 2)(x – 4) is a possible function.
